SHUTTLEFEELER THR-EAD CUTTER.

Application filed January To all 107mm t may concern.'

Be it known that I, ALONZO E. RHoADEs, a citizen of the United States,residing at Hopedale, in the county of VVorcester and State ofMassachusetts, have invented an Improvement in Shuttle-Feeler ThreadCutters, of which the following description, in connection with theaccompanying drawings, is a Specification, like `characters on thedrawings representing like parts.

This invention relates to Shuttle feeler thread parters or cutterswhereby the spent filling between the cloth selvage and shuttle isparted when filling replenishment is to be effected.

As now ordinarily constructed, shuttle feel er thread cuttersare'mounted upon the shuttle feeler' and move with it to its rearwardshuttle feeling position, one of the parters being fixed to the shuttlefeeler and the other being actuated by lay movement to sever or part thefilling as the lay moves toward its front position.

The present invention differs from such shuttle feeler thread parters inthat the pi'esent invention provides two parting members each of whichis Supported upon the shuttle feeler for movement relative thereto topart the filling thread. In carrying` the 3" invention into practicaleffect, one `of the parting members or blades is shown as pivotallySupported upon the shuttle feeler and provided with a heel to be struckby the lay as the latter moves frontwardly to give to the parter orblade its parting movement, vand associated with such parting member orblade is another parting member or blade also mounted on the feeler formovement in the performance of its cutting or parting function. Ineffecting movement of the two parting members or blades simultaneouslyto out or part the thread, one of them is actuated at the proper time,and preferably by lay movement, and connections are provided between thetwo parting members or blades Such that when the lay operated parter orblade is actuated, the other parter or blade will be Simultaneouslyactuated, so that the lling thread will be cut or parted by the combinedaction of the two parting mem` bers or blades.

It is now the usual practice to provide the shuttle feeler with somekind of a clamp, to clamp the end of the filling thread leading to thecloth Selvage and to carry the end 17, 1925. Serial No. 3,051.

frontwardly in order that the portion of such end adjacent the clothselvage Shall be properly presented to the temple ithread cutter. InpriorV constructions it has been the usual practice to` form the clampas a part fixed tothe shuttle feeler andsometimes to clamp the end ofthe thread between such stationary clamping member and a movable threadparter or blade. In accord ance with the present invention, the clampingmember is mounted on the shuttle feel# er for movement relativelythereto to clamp the end of the thread leading to the cloth selvagebetween itself and one of the threadparters or blades.V Such movementofthe clamping member gives an increased hold on the end of the threadand `prevents its being withdrawn from the clamp as the shuttle feelermoves to front position.

The invention and new combination of parts will best be made clear fromthe following description and the Vaccompanying drawings of one goodform thereof.

In the drawings:

Fig. l is a Side elevation of av shuttle `feeler provided with thepresent invention,"some of the loom parts beingomitted;

Fig. 2 is a detail of the thread parter showing the two members thereofas having been moved to cut or part the thread;

Fig. 3 is a top view partly in Section showing the pin and lslotconnectionv between the two members of the parter and between one of themembers of the and Fig. 4 is an enlarged front detail Showing theposition "of the parts after the cutting operation.

The loom frame 1 may be of any usual or desired character and, as shown,has connected thereto a bracketlon which is pivotally mounted at 2 theshuttle feeler 3, the rearwardly extending end portion 4c of which isprovided with an opening 5, as usual. Extending from the shuttle feeleris a lug or pin 6 which is engagedby the jaws 7, 8 which are actuatedvfrom an indicating mechanism, (not shown) "for moving the shuttlefeeler to its rearwardfshuttle feeling position when an indication has-been made for replenislnnentof fillingor other change in the loomopera-tion. y

The shuttle feeler issho'wn in the present instance as being guided inits movement towards and from the front of the loom by a parter and theclamp;

loo p end portion of the primary par-ter member 10 is the heel 12 whichis adapted to be struck by the lay as it moves towards front position toactuate the parter members to part or cut the thread. In the presentinstance of the invention the lay 13 has a striking member or bun-ter 14mounted thereon,

which is adapted to engage the heel 12 when the shuttle feeler is in itsrearward shuttle feeling position and the parting members are open, asshown, to thereby eect movement of the parting members in their part ingor cutting operation. If desired, the primary parting member 10 may havea cutting edge 15.

Mounted upon the shuttle feeler '3 is the thread parter or blade 16which may for identification be known as the secondary parter-member,and is here shown as provided with a large opening 17 through whichpasses the bolt 11 on which bolt the '"1 primary parter member ispivotally mounted. The secondary parter member 16 has a cutting edge 18and is pivotally supported on a pin 19 extending laterally from 4theshuttle feeler 3 and passing through an .opening 2O formed in theprimary parter member. The enlarged opening 17 which is formed fin thesecondary parter member 16 permits movement of the secondary partermember about its pivotal support 19, and yet affords means for limitingsuch movement.

In accordance with the 'present invention, the two parter members 10 and16 are to be moved relative to the shuttle feeler in the performance oftheir parting function, and as one means for effecting movement of thesecondary parter member by movement of the primary partenmember, thelatter is here shown as provided with a pin 21 eX- tending laterallythereof and engaging a recess .or opening 22 formed in the secondaryparter member. The recessr 22 in the sec-I ondary parter member isformed on a vcurve which is eccentric to the pivotal axisof theprimaryparter member 10 -or pin 11, the result being that when theprimary parteil member is actuated by lay movement from the positionindicated in Fig. 1 to that of Fig. 2, the pin 21 riding in the-eccentric slot 22 will effect simultaneous movement of the secondarypartei' member,- so `that both parter members will partake of the movement in their cutting function. In Fig. 1 the line a indicates acircular path concentric to the axis of the primary parter member 10 andit will be noted that the slot 22 is eccentric thereto.

In some cases it may be desirable to provide a clamp for holding orclamping the end of the filling thread leading to the cloth selvage, andas shown herein, such clamp may be formed by a clamping member 23preferably mounted on the shuttl-e feeler at the side ofthe primaryparting member 10, as indicated in Fig. 3. The clamping member 23 has anend portion 24 between which andl theside of the primary parter member10 the thread b may be clamped, as indicated in Fig. 4. In the presentinstance vthe clamping member 23 is provided with the bifurcated endportion 25 which embraces the pin 19 on which the secondary partermember is pivoted, and the clamping member is provided with an opening26-'similar yto the opening 22 formed in the secondary parter member andarranged eccentrically to the pivotal support of the primary partermember 10. Extending laterally from the primary parter member 10 is thepin 27, Fig. 3, which engages the eccentric opening 26 in the clampingmember, and the clamping member 23 is also provided with an enlargedopening similar to th-e opening 17 formed in the secondary partermemberl and embracing the stud or pin 11, the construction being suchthat upon actuation of the primary parter member by lay movement, boththe secondary parter member and the clamping member will be moved abouttheir pivotal supports to cooperate with the primary parter m-ember topart the thread and clamp it between the primary parter member and gheclamp-ing member 23, as indicated in The bolt 11 on which .the primaryparter member 10 is pivoted and which alsopasses through the enlargedopening 17 of the secondary parter member and a similar opening in theclamping member 23, may be provided with a spring washer 28, asindicated in Fig. 3, for holding the parts in their assembled relation,as indicated. As shown` the primary parter member 10 is disposed betweenthe secondary parter member 16 and the clamping member 23, but inaccordance with the present invention, this particular relation of parts`may not always be necessary.

From the construction described as a goed practical form of the presentinvention, it

will be noted that the thread parter comprises two parter members orblades mounted upon the shuttle feeler for movement relatively theretoin the performance of the thread parting and cutting function, and that,as shown, such movement of the two Las-ases parter members or blades isefected by connections between the two which ltransmit movement of oneof the parter members or blades to the other parter` member or blade.

As shown, also, the invention further comprises a clamping member which`is moved during the operation of the parting members to clamp the end ofthe filling between one of the parting members and the. movable clamp. v

The heel 12 of the primary parter member l0`is provided with a pin 29whereby the primary parter member may be moved to its open position asthe shuttle feeler is moved to its rearward shuttle feeling position,and, of course, simultaneously, the secondary parter member will bemoved to its open position. Any suitable means may be employed foropening the members of the parter as the shuttle feeler moves torearward position, but in the present instance of the invention, thebracket l has secured thereto at 30 the upstanding trip arm 3l on whichis pivotally supported at 32 the trip 33 which may be of usualconstruction and adapted to operate upon the pin 29 of the primarymember, as the shuttle feeler moves to rearward position to open theparter members as the pin 29 rides along` the inclined surface 34 of thetrip. When the two movable parter members have been closed upon eachother to part the thread and the shuttle feeler is moved to its frontposition, the pin 29 will ride under the trip 33, lift the same, andthen pass frontwardly thereof, the parter members still remaining closedand the clamping member still remaining in its holding or clampingrelation with one of the parter members. As the shuttle feeler moves toits rearward feeling position, the pin 29 will effect opening movementof the parting members and also of the clamp. The trip 33, as shown, hasa stop 35 which is adapted to engage a stop 36 on the upstanding arm 3lto limit backward swinging movement of the trip.
